Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design
1. Title: Casing
2. Objective: To design the Casing with sheet metal from Nx CAD
3. Introduction: The sheet metal working domain is widely used in industries because sheet metal can quickly get and does not require any type of machining process like turning, milling, boring or any other kind of process which can be done with the help of CNC or VMC machine. In the Sheet metal process, the power utilization and material wastage are very less. So it is money and time saving also, by which the cost of sheet metal parts little bit reduces. We can manufacture a part which will have good strength and rigidity like a part modelling.
The casing name is suggesting to Case of any machine parts and tightening to restrict the moment of other parts in any machine.
4. Design Approach:
--Rectangle Sketch of 50x60
-- Tab of 1mm
-- cut of 40x 5 from the left-hand side edge from the centre line
-- edge bend from the Upper side and lower side of 15 mm with respect to the horizontal centre line (cd 30 mm)
-- Break the corners by 1 mm blend
-- Unbend the plate from the respected bending edges
-- mark all corners for M2 clearance hole
-- 4xM2 clearance hole
-- Draw the Sketch at the centre of the plate for making a dimple (emboss)
-- sketch a 5 mm diameter circle by an offset of 8x8 mm from the bending corner for making beads
-- mirror them and make 4 corner beads
-- Rebend from the corners and ready casing
-- Flat pattern to make drafting
5. Description:
Sketch -- 2d sketch drawn for making the sheet metal of 1 mm and other features like dimples, and beads.
Normal Cut: Cut the sheet according to the requirements
Bend: bend the sheet with respect to their bending lines
Flange: make the flanges from the end edges of sheet metal according to the requirements
Unbend: Make the flat sheet metal plate
Hole: To make the hole of different types and various requirements
Dimple: To make the emboss-like structure
Beads: To make this is also made to emboss structure but a circle sketch is required
Mirror Feature: To make duplicate features with respect to the XY, YZ or ZX plane
Rebend: Rebend the sheet metal with respect to its bending edges.
Flat Pattern: To make flat sheet metal for drafting details

8. Conclusion: In this project, we learned the different tools and features used to make sheet metal parts in NX CAD software and also learned how to do detailed drafting.
